Great length and great feel

Finally a thermal top that you can tuck in!
I tested these thermals out on a recent camping trip in the Snowy’s, and they did not let me down. Super comfy and a great fit.

Great Tees

Great tees for general use and travelling. Comfy on long flights - just right in terms of warmth and can wear them for several days before they need a wash

Versatile and extremely comfortable

Getting plenty of use out of my new thermal top. So comfortable as a base layer on chilly Melbourne mornings and out on hikes in the bush.

Merino Thermals FAQs

In thermals, you need stretch. This is so they sit nice and close to the skin and provide the best insulative qualities. Pure merino is stretchy but not quite enough. Our Australian merino/elastane blend gives you softness, stretchiness, as well as all the benefits of merino.

Why not?

You don't know you're missing a pocket until you need one. You're at Clinton Hut on the Milford Track or at a campsite on the Larapinta Track. Just in your thermal clobber—we hikers/trampers are all about high-fashion, after all—and you've nowhere to pop your headlamp or phone or pack of matches. Nice for warming the hands too.

Same as with t-shirts. 30 days. No fuss. We're happy to do size and change of mind exchanges or credits or refunds. They just need to come back to us in pristine, resellable condition. Email before returning any items though so we can walk you through the process.

Oh, and with the bottoms, make sure you try them on with your undies on.

If you place an order now and choose to cancel the order before the thermals arrive that's perfectly fine. A credit or exchange or full refund is available - your choice.

Ah, the logistics of manufacturing clothing.

The charcoal marle these will be produced in are a 'custom colour' with our manufacturer. We sampled in black as we developed the product. So we had to get a bit creative in Photoshop for the initial product photos, just until we get out batch of photography samples and we do a full photoshoot. Hopefully in Kosciuszko National Park which'll be a stunning backdrop!

Around 35gsm in weight for a start. Our lightweight 100% merino tee is 165gsm and our thermals are 200gsm. Perfect for cooler conditions. And, our thermals are a merino/elastane blend, which lends itself a bit better to 'baselayer' wear.
